6 predictions · 454 assertions · 38 opinions · 280 insights · 18 disclosures · 4 what ifs · every statement was checked. The predictions and assertions are the 460 claims: statements the public record can support or contradict. 412 are resolved, 14 are not yet assessed, and 34 name no date, number or outcome precise enough to check. Everything else (opinions, insights, what ifs, disclosures) can never be settled by the record, so it carries no assessment.

Expressed certainty vs assessment result

How they sound: not measured why? →
We measure speaking style by listening to the audio itself, and a fair number needs at least 2,000 words from one person on tape we have measured. There is too little of Shane Parrish on measured tape to publish a rate. This says nothing about how they speak.

Mackey: Clear grocery health ratings will drive away shoppers or get diluted
